WOW had none... In fact WOW didn't even have high level instances when it was released, they just had Blackrock Mountain... Ah those were the days... When the game was played by those who enjoyed MMO's and not the idea of casual gaming... MMO's are built for their vast worlds, later comes the epic dungeons... If you need more excitement then stop playing MMO's and go play Modern Warfare 3. Content takes time and most hardcore MMO fans understand this... I love how so many WOW players like to compare a brand new game (SWTOR) to a game that has been in post-release developed since Dec 2004 (WOW)...

World of Warcraft regularly implemented armor updates. In the beginning of WOW the "Valor" armor set for the plate wearer was ******... then Blizzard updated it and gave everyone a set of armor more ridiculous then a golden samurai from the 60's.
